build an array of mysql query?

Could someone please let me know how I can create an array from the MYSQL query?

The array should look like this:

<?php
$testLocs = array(
    '1' => array( 'info' => '1. New Random info and new position', 'lat' => 45345345, 'lng' => 44.9634 ),
    '2' => array( 'ino'  => '1. New Random info and new position', 'lat' => 686788787, 'lng' => 188.9634),
    '3' => array( 'info' => '1. New Random info and new position', 'lat' => 88888, 'lng' => 144.9634),
    '4' => array( 'info' => '1. New Random info and new position', 'lat' => 666666, 'lng' => 144.964 )
);
echo json_encode($testLocs);
exit();
?>

where the Texts for info and numbers for lat and lng are mysql $rows.

Any help would be appreciated.
